When Speedy had difficulty picking up the canter, she realized that I was putting my outside thigh too far back. She instructed me to swing my leg back from the knee only which helped me keep my seat bones in the saddle.
We retackled my sitting trot, but this time, she insisted I sit back and she reminded me every single stride. I finally realized that she wasn't talking about my shoulders only, but that she meant to sit back ON my seat bones. Yeah, I've only heard that about 10,000 times, but with her relentless coaching, I finally plugged my seat into that saddle and kept it there. I couldn't help it; I smiled!
